i see some differences, but not big enough to sneeze at.

comparing the 2 volcano scenes- the lighting, textures, particle effects, etc all look a lot worse on the ps4

Someone mentioned that PC demo was running on 3x GPU. That alone makes a big difference does it not?

I wouldn't say the PS4 version looks bad by any stretch.

You're potentially talking about a comparison between a $450-$550 console to a PC that had ~$1200-$1500 worth of GPUs.


It's running on a single GPU at 1080p and 60fps on the PC

Yeah, I just saw that. As I said though in my newer post, that GPU alone costs ~$500.

Yeah PC's do more, but I don't think that's what we are comparing, it's just a graphics comparison at this point, to get a feel for how the PS4 stacks up to a "current" high end PC

I know. It's just that I don't feel that the difference is anything to make a big deal out of. It definitely is nowhere close to how to how it was back in 2007 with Crysis against say, Resistance.

The screens I showed display the fact that the PS4 version is missing some things here and there, but overall, when compared to the PC it is pretty impressive.



iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.

Currently playing:

Final Fantasy VI (iOS), Final Fantasy: Record Keeper (iOS) & Dragon Quest V (iOS)     

    

Got a retro room? Post it here!

The PC version looks better in every way, but I doubt you'd be able to see all that much of a difference in actual gameplay.



one of the bigger differences is 1080p against 720p. that's already a huge difference in needed power. 



The demo changed from the last year... so the comparisons are a bit hard.

And about my 3xGPU... it's true... but I was wrong about the demo... the Samaritan used 3-way SLI GTX 580... the Elemental use a single GTX 680.

Some guys in the Beyond3D are saying the Epic changed the Demo for PS4 because the lack of RAM... they create the Demo using 4GB of RAM so some techs are removed from the first Demo.... they think we will see a full PS4 Demo (created for the 8GB) soon.

Anyway there some graphics techs that can be used only with a lot of RAM like Voxel cone tracing for GI and shadows.

Anybody have the full specs of the PC running the Elemental Demo???

If its true, but about the wrong demo, then... well, thats not true. 

 

As far as RAM goes, the GTX 680 is a 2gb card. Now why wouldn't the PS4 version look better then the 680 PC version?

Hint; it has to do with fillrate and pixel shader rate. IE 8gb of ram is removing 1 bottleneck from the system, but other bottlenecks still remain.

You forget the main PC RAM used in the Demo... PS4 4GB (now 8GB) is for CPU and GPU... the Demo runs with a GTX 680 with 2GB + CPU with XGB... this demo needs more than 4GB of RAM I guess.

That's what the guy in Beyond3D said... seems like the Demo was changed to remove some tech that use a big amont of RAM.



Just for clarification, 680 is some 50-60% faster than what's inside PS4.

And the GPUs VRAM is the only thing being used to draw what you see on screen. Thats it, 2gb for all those textures, lights, particles, ect.

The main RAM in a computer is used by the CPU, and only the CPU. To give you some point of reference, crysis 2 uses about 800mb of system ram., ie what the CPU is using.

Battlefield uses ~1400MB... now get the PS4 4GB RAM unified and remove the OS part (1GB?) and you have 3GB for the game.

I'm pretty sure the Elemental Demo uses more than 3GB RAM (GPU + CPU).
